Math 261y: von Neumann Algebras (Lecture 3)
September 7, 2011 In this lecture, we continue our study of C ∗ -algebras. Recall that C ∗ -algebra is a Banach algebra equipped with an anti-involution x 7→ x∗ satisfying ||x||2 = ||x∗ x||. Notation 1. Let A be a ∗-algebra. We say that an element x ∈ A is Hermitian or self-adjoint if x = x∗ . We say that x is skew-Hermitian or skew-adjoint if x∗ = −x. Every element x ∈ A admits a unique decomposition ∗ ∗ is self-adjoint and i=(x) = x−x is skew-adjoint. x =
